摘 要 :目的 :分析4个无综合征耳聋家系是否存在线粒体DNA1555A→G 的突变。方法 :以PCR-RFLP方法进行线粒体DNA1555A→G 突变筛查。结果 :仅1个无综合征耳聋家系中的5个成员有4个存在该突变。结论 :线粒体DNA1555A→G 点突变与部分无综合征耳聋有一定关系。

Abstract : Objective : To analysis whether there is anymtDNA 1555A →G homoplasmic point mutation among familial nonsyndromic deafness.Method: Polymerase chain reaction andrestriction fragment length polymorphism (PCR-RFLP) were used to screen the mutation 1555A →G among four nonsyndromicdeafness families.Result : The same mutations were checked out in 4 of 5 individuals in 1 of 4families.Conclusion : The 1555A →G change on mtDNA might be one of the multiple geneticdefects and pathogenetic of familial nonsyndromic deafness.
